CATCH-BASIN COVER.

SPECIFICATION forming part of Letters Patent No. 430,620, dated June 24, 1890.

I Application filed November 16 1889. Serial No. 330,518. (No model.)

To 01/ whom it may concern:

Be it known that I, GEORGE GARDINER CAMPBELL, of Milwaukee, in the county of Milwaukee and State of WVisconsin, have invented new and useful Improvements in Catch-Basin Covers; and I do hereby declare the following to be a full, clear, and exact de scription of said invention, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in that class of catch-basin covers for which Patents Nos. 204,882 and 374,393 were issued to me on June 18, 1878, and December 6, 1887, respectively.

In the drawings, Figure 1 is a vertical section of my improved device on line 1 1 of Fig. 2. Fig. 2 is a top view or plan of my improved device. Fig. 3 is a top view or plan of a slightly-modified form of my device adapted for use at the corner of a street, the device being shown in connection with so much of the sidewalk and street-pavement as is necessary to show its relation thereto.

A circular base-plate Ais provided with an inner downwardly-extending flange B and an outer downwardly-extending flange O entirely around it. This base-plate and the flanges B and 0 form a channel beneath the baseplate, within which the top of the wall D is adapted to be received and protected. From the inner edge of the base-plate A a wall E extends vertically around a portion of the inner edge of the base-plate, and around the remainder of the catch-basin cover are located at short distances apart bars F F, extending downwardly from a top plate G at an inclination outwardly to the base-plate A. The plate G is located horizontally at the top of the wall A, and the bars F F extend at an inclination and radially from the plate G to the outer edge of the plate A. These radial bars F F are located about all that part of the cover that adjoins the pavement of the street, while the vertical wall E is about that part which abuts against the sidewalk or part of the street that is raised above the pavement alongside thereof. The bars F F serve as guards to prevent large objects from entering the catchbasin, and also, as they'are inclined and terminate at the pavement, they serve to keep the wheels of passing vehicles on the pavement and off the base-plate, or from striking any other part of the cover. An aperture or man-hole in the plate G is closed by a cover H. As the base-plate A with its flanges B and 0 form a channel, within which the wall D is received, the catch-basin cover is thereby held in position directly above the well or aperture within the wall D, and at the same time the top of the wall D is covered and protected from wear or injurv.

The sidewalk I rests on the base-plate A throughout so much of the plate as is within the line of the sidewalk, while the pavement K is built up to and against the base-plate and flange C oppositeall that part of the base-plate which is beyond the line of the sidewalk. The catch-basin cover is formed of iron and is cast integrally, except only the removable cover H.

What I claim as new, and desire to secure by Letters Patent, is E An integral metal catch-basin cover, consisting of a circular flat horizontal base-plate, circular flanges extending downwardly vertically from the inner and outer edges of the base-plate, respectively, a vertical wall projecting upwardly from the base-plate at its inner edge and extending partially around the base-plate, a horizontal top plate at the top of the vertical wall, and inclined radial bars at a distance apart extending from the top plate to the top surface and outer edge of the base-plate about that part of the baseplate and top plate not connected together directly by the vertical wall, the bars widening radially downwardly, so that at their lower ends they are as wide as the base-plate, completely protecting it, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE GARDINER CAMPBELL.
